0.28 Inch LED Digital Display USB Voltmeter Ammeter Dual Display Voltage Current Meter USB Detector Battery Capacity Tester Red

Features: USB dual meter is small in size It can display USB charging or discharging voltage and current at the same time and on the same screen, alternately or single display capacity and power Adopt USB extension cable input, output at both ends, easy to use The USB double meter adopts exquisite SMT craftsmanship, so the consistency is very good Built-in intelligent charging identification IC, which can automatically match high current charging Product parameters: Product name: USB test table Display mode: 0.28""LED, single color (full red), double color (red and blue) color optional Product size: 69×26×19mm USB extension cable: ≥120mm Measurement accuracy: 0.1% (±3 digits) Measurement rate: ≥500mS/time Working temperature: -10～+65℃ Working air pressure: 80～106kPa Working humidity: 10～80% (no condensation) Sun exposure: no direct sunlight Input voltage Test voltage: 3.20-30.0V (automatic shift of decimal point) Resolution below 10V: 0.01V Resolution above 10V: 0.1V Test current: 0.00-3.00A (up to 10A, can not work for a long time) Resolution: 0.01A Automatic identification: OUTPUT Ⅱ has built-in intelligent charging control IC, which can automatically match your mobile phone and tablet with suitable and safe high-current charging QC2.0 QC3.0: OUTPUTI supports Qualcomm QC2.0, QC3.0 charging (Note, when using QC2.0, QC3.0 charging, OUTPUT II cannot be plugged into other devices) Capacity test: 0-99999mA/H (ie 99.999A/H) Capacity accumulation: in the case of uninterrupted power, the accumulation of N times of charging capacity Capacity check: 1. Power on without connecting any USB device, the displayed capacity is the last accumulated capacity, and the accumulated capacity has a power-off memory function                 2. After the power-on capacity is cleared, the displayed capacity is the accumulated capacity of the current N times of charging or discharging.                 3. You can switch to view by pressing the button Capacity reset: 1. When the power is turned on and recharged after a power failure, the last accumulated capacity """flashes twice""" is cleared to zero.                 2. Long press the button to accumulate the capacity and the accumulative capacity ""flash twice"""clear to zero" Power test: 0.00-9.99-99.9W, the decimal point is automatically shifted Overvoltage alarm: when the voltage is >/=5.6V, the voltage decimal point - flashes quickly Undervoltage alarm: when the voltage is Overcurrent alarm: when the current >/=3A, the current decimal point - flashes quickly Short circuit alarm: current decimal point - flash quickly Button: One button, you can switch 7 different display modes: only VA, only C, and only P-VA+C-VA+P-C+P-VA+C+P, long press the button to clear the accumulated capacity alarm When prompted, you can long press the button to cancel the alarm prompt function Shipping list: USB Tester X1
